Procedure

5-Chloromethyl-3-(2,5-difluoro-phenyl)-[1,2,4]oxadiazole (23 mg, 0.10 mmol) and 4-ethyl-5-thiophen-2-yl-2,4-dihydro-[1,2,4]triazole-3-thione (23 mg, 0.11 mmol) was dissolved in anhydrous DMF (1 ml) and potassium carbonate (21 mg, 0.15 mmol) was added. After stirring for 22 h ethyl acetate was added, the resulting mixture was washed twice with water and once with brine, dried over MgSO4 and evaporated. Flash chromatography using heptane:ethyl acetate 1:1 yielded the title compound (20 mg, 50%).
